Jackie Warner Training Tip #2: Turn up the intensity

Long, boring workouts aren't the best way to lose weight. "How long you work out isn't as important as how strong you work out," Warner says. You can get great results from a short (10- to 20-minute) high-intensity workout, making it easy to fit exercise into your busy schedule.

Jackie Warner Diet Tip #3: Avoid fat-free food

Don't let food labels fool you. Many fat-free foods are actually loaded with sugar. And too much sugar is often the real reason people gain weight, Warner says. More importantly, your brain doesn't work as well when you eat a lot of sugar. Candy, cookies and soda aren't the only problem. Sugar is in virtually every food you eat. "Breads, crackers, pretzels, chips—that's sugar."

Jackie Warner Training Tip #4: Don't be afraid to lift weights

A lot of women don't want to start a weight-training program because they're afraid to bulk up. But you can't get a toned and tight body without lifting weights, Warner says. Resistance training adds much needed muscle to speed up your metabolism. For the best results, focus on working the biggest muscle groups—chest, back, butt and legs.

Jackie Warner Diet Tip #5: Eat the good, the bad, then the ugly.

Classify the food you eat as good (veggies, fruit,lean meats), bad (starches, bread), and ugly (dessert, alcohol). Fill up on the good first and then move on to the other foods. "Last night, I ordered a salad, a hamburger and truffle fries. I ate the salad first, and then about three bites of the burger and four truffle fries. I usually just want the taste of that rich, decadent food."
